I'll keep that in mind, thank you.

I'm now getting to the 386 syscalls.  The following comment in the
mkfile needs addressing.  Suggestions?

# _SEEK is broken, but we currently don't use it.
# GCC uses eax,edx to return a vlong
#
#			if(~ $i _SEEK) {
#				echo 'CMPL AX,$-1
#				JNE 4(PC)
#				MOVL a+0(FP),CX
#				MOVL AX,0(CX)
#				MOVL AX,4(CX)'
#			}

Much appreciated.  How much of the p9p work am I duplicating right
now?
